JAMES W. FARltELL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOE OF ONE-HALF TO STEPHEN FLANAGAN, OF SAME PLACE.

AClDlNG-MACHINE FOR MAKING SHEET-METAL CANS.

SPECIFICATION forming part of Letters Patent No. 248,255, dated October 11, 1881.

Application filed August 18, 1881. (No model.) i

To all whom it may concern:

Be it known that I, JAMES W. FARRELL, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in A-ciding-Machines for Making Sheet-Metal Cans, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure l is a top or plan view of the acidingmachine embodying my invention. Fig. 2 is a vertical section thereof in line :0 m, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to improvements in machines or apparatus for applying acid or flux to cans prior to dipping or soldering; and it consists of a brush and an acid-holder rotating together and a concentric can-supporter. The brush is adjacent to the supporter, and, being fed with acid, applies the same around the can in a convenient, quick, and uniform manner. Provision is made for adjusting the apparatus to cans of different sizes and requirements.

Referring to the drawings, A represents a trough or pan, which is properly supported, and B represents an upright shaft, which is passed through the center'of the pan and sustained on a step, at, below the bottom thereof.

To the top of the shaft B is secured a head, 0, for holding the can to be subjected to the aciding process, the same being preferably of conical form, the widest part being below.

D represents arms connected to a rotary sleeve, E, which encircles the shaft B and carries at its lower or outer end a bevel-pinion,b, with which meshes a wheel, 0, keyed or otherwise secured to the driving-shaft F of the machine; but other gearing than the pinions b 0 maybe employed for rotating the sleeve E and connected parts.

On the upper portion of the arms D are supported the acid-holders G, consisting of suitable boxes or pans, which are provided with discharge-spouts and suitable cocks, as at d,

- said spouts extending inwardly toward each other, and having'their outer ends adjacent to brushes H, which are connected to the arms D and surround the can-holding be 1d 0, a single brush or a number of brushes being employed, as desired.

The holders G .are supplied with acid and the cocks at opened, whereby the acid flows from the spouts to the brushes H. Power is applied to the driving-shaft F, and the can is then placed on the head 0, the rod or shaft B remaining stationary on the step a. The brushes rotating with the arms D comein contact with the lower end of the can, or the flange thereof, and apply the acid thereto, after which the can is removed, reversed, and reapplied,if so required or desired, and the can is ready to have its heads soldered to it, the operation of aciding being accomplished in an inexpensive, expeditious, and uniform manner. The drip from the brushes and can falls into the pan A, from whence it may be gathered and returned to the holders G.

The step a is provided with a set-screw, J, which tightens against rod or shaft B and atfords means for holding said shaft at various heights, so as to adjust the headG higher and lower relatively to requirements of the can and the brushes. The arms D are each formed of separated parts, which are connected by a screw or bolt, K, which passes through aslot, e, in one part, and is fitted to the other part so that the arm may be vertically adjusted rela-r tively to the height required to set the brushes and acid-holder.

The brushes have slotted heads, through which are passed screws or bolts L, connected to the arms D, whereby the brushes may be set nearer to and farther from the head Oand press to a greater or less extent against the can,for adjusting the quantity of acid to be placed thereon.

When the several parts are adjusted the respective set-screws are tightened and the parts retain their adjustments.

It is evident that the rod or shaft B may be provided with gearing connected to the driviug-shaft F, for rotating the head 0, and consequently the can on said head, in which case the arms D are made stationary, and the can moves around the brushes.

Having thus described my invention, what I 3.
